Problems solved by technology

The propagation speed of split root method is very slow, the seedlings produced are uneven, the number of branches is different, the root system is large and small, and the age of seedlings cannot be defined, which cannot meet the requirements of commercial seedlings, which affects the commercial production of purple spot peony. quality
Although the sowing method can increase the number of reproduction, but because the stamens and stamens of the better varieties of Gansu peony degenerate, the amount of seeds set is small, and the single-petal varieties with poor quality have a large amount of seeds, which makes the more degenerate the variety after sowing and reproduction, and it is impossible to make high-quality peonies. A large number of species and rare species have been multiplied, and it cannot meet people's viewing needs for fine varieties of peonies in Gansu

Example Embodiment

[0039] Example 1. In this embodiment, peony root is used as the rootstock. A method for commercialized production of purple spotted peony grafting and rapid propagation, including the following steps:

[0040] (1) Establish a good variety scion collection nursery: In the scion collection nursery, excellent Gansu purple-spotted peony varieties are planted and planted according to the color system. The plant row spacing is 2m×2m, and there are more than 100 varieties. Each plant is numbered and listed for registration. On average, the ear-picking nurseries are inspected every 15 days, the plants with pests and diseases are sprayed in time, and the severe ones are immediately dug out and destroyed to prevent infection. Apply farmyard manure once every October to the whole nursery at a rate of 1500 kg / mu, and apply topdressing once in March with a rate of 20 kg / mu. Prune regularly to ensure a healthy female parent.

[0041] (2) Establish a peony rootstock production nursery: The roots...

Example Embodiment

[0061] Example 2. In this embodiment, peony root is used as the rootstock. A method for commercialized production of purple spotted peony grafting and rapid propagation, including the following steps:

[0062] (1) Establish a good variety scion collection nursery: In the scion collection nursery, excellent Gansu purple-spotted peony varieties are planted. They are classified and planted according to the color system. The row spacing is 2m×2m, and there are more than 100 varieties. Each plant is numbered and listed for registration. On average, the ear-picking nurseries are inspected every 15 days. Plants with plant diseases and insect pests are sprayed in time, and the severe ones are immediately dug out and destroyed to prevent infection. Apply farmyard manure once in the whole nursery in October every year, with a fertilizer rate of 1500 kg / mu, and apply topdressing once in March with a fertilizer rate of 20 kg / mu. Prune regularly to ensure that the female parent is healthy.

Abstract

The invention discloses a rapid grafting propagation method for commercial production of paeonia rockii, and relates to the fields of grafting and propagation of flowers. The method comprises the following steps: establishing a fine variety scion collecting garden, establishing a rootstock production garden, preparing before grafting, selecting rootstocks, collecting scions, sterilizing the scions, sampling inspection, grafting, storing in sand, managing the sand storage, taking out of a greenhouse, planting and the like. The method helps determine a principle for selecting a grafting time based on temperature, thus improving the survival rate of the rare species (the paeonia rockii) from original 35% to more than 75%, causing large-scale propagation of the paeonia rockii to be possible, and providing a technical guarantee for the commercial production. The method helps realize the desire that the paeonia rockii in Gansu blossoms in any cold areas, and also meets the requirements of people from different areas for admiring rare species.

Description

technical field [0001] The invention relates to a method for grafting and rapid propagation of flowers, in particular to a method for grafting and rapid propagation of Gansu purple spot peony commercially produced. Background technique [0002] Gansu is an important birthplace of Chinese peonies. Gansu purple spot peonies are resistant to cold and drought, with tall plants, large and colorful flowers, strong aroma, strong resistance to diseases and insect pests, and wide adaptability. Artificial protection measures can survive the winter in the open field, which is different from the Central Plains peonies mainly in Luoyang, Henan and Heze, Shandong. However, due to the influence of traditional factors, coupled with the lack of specialized research on Gansu peony, especially the long-term unresolved reproductive problems, Gansu purple spot peony cannot be industrialized and commercialized. There are mainly the following problems: [0003] 1. The reproductive technology is b...
